Gillette Venus Extra Smooth Womens Razor Blade Refills, 6 ct

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number.

A blade is the sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut. This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modern versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks.

Blades function by concentrating force at the cutting edge. Design variations, such as serrated edges found on bread knives and saws, serve to enhance this force concentration, adapting blades for specific functions and materials. Blades thus hold a significant place both historically and in contemporary society, reflecting an evolution in material technology and utility.

Gillette is an American brand of safety razors and other personal care products including shaving supplies, owned by the multi-national corporation Procter & Gamble (P&G). Based in Boston, Massachusetts, United States, it was owned by The Gillette Company, a supplier of products under various brands until that company merged into P&G in 2005. The Gillette Company was founded by King C. Gillette in 1901 as a safety razor manufacturer.

Under the leadership of Colman M. Mockler Jr. as CEO from 1975 to 1991, the company was the target of multiple takeover attempts from Ronald Perelman and Coniston Partners. In January 2005, Procter & Gamble announced plans to merge with the Gillette Company.

The Gillette Company's assets were incorporated into a P&G unit known internally as "Global Gillette". In July 2007, Global Gillette was dissolved and incorporated into Procter & Gamble's other two main divisions, Procter & Gamble Beauty and Procter & Gamble Household Care. Gillette's brands and products were divided between the two accordingly. The Gillette R&D center in Boston, Massachusetts, and the Gillette South Boston Manufacturing Center (known as "Gillette World Shaving Headquarters"), still exist as functional working locations under the Procter & Gamble-owned Gillette brand name. Gillette's subsidiaries Braun and Oral-B, among others, have also been retained by P&G.

A razor is a bladed tool primarily used in the removal of body hair through the act of shaving. Kinds of razors include straight razors, safety razors, disposable razors, and electric razors.

While the razor has been in existence since before the Bronze Age (the oldest razor-like object has been dated to 18,000 BC), the most common types of razors currently used are the safety razor and the electric razor.

Venus is the second planet from the Sun. It is often called Earth's "twin" or "sister" planet for having almost the same size and mass, and the closest orbit to Earth's. While both are rocky planets, Venus has an atmosphere much thicker and denser than Earth and any other rocky body in the Solar System. Its atmosphere is composed of mostly carbon dioxide (CO₂), with a global sulfuric acid cloud cover and no liquid water. At the mean surface level the atmosphere reaches a temperature of 737 K (464 °C; 867 °F) and a pressure 92 times greater than Earth's at sea level, turning the lowest layer of the atmosphere into a supercritical fluid. Venus is the third brightest object in Earth's sky, after the Moon and the Sun, and, like Mercury, appears always relatively close to the Sun, either as a "morning star" or an "evening star", resulting from orbiting closer (inferior) to the Sun than Earth.

The orbits of Venus and Earth make the two planets approach each other in synodic periods of 1.6 years. In the course of this Venus comes closer to Earth than any other planet, while on average Mercury stays closer to Earth (and any other planet) due to its more inferior orbit. For interplanetary flights Venus is a frequently taken and often energy and time saving waypoint, performing gravity assisted flybys. Venus has no moons and has a very slow retrograde rotation about its axis, a result of competing forces of solar tidal locking and differential heating of Venus's massive atmosphere. As a result a Venusian day is 116.75 Earth days long, about half a Venusian solar year, which is 224.7 Earth days long.

Venus has a weak magnetosphere, lacking an internal dynamo it is induced by the solar wind interacting with the atmosphere. Internally, Venus has a core, mantle, and crust. Internal heat escapes through active volcanism, resulting in resurfacing, instead of plate tectonics. Venus may have had liquid surface water early in its history with a habitable environment, before a runaway greenhouse effect evaporated any water and turned Venus into its present state. Conditions at the cloud layer of Venus have been identified as possibly favourable for life on Venus, with possible biomarkers having been found in 2020, which has spurred new research and missions to Venus.

Humans have been observing Venus throughout history across the globe, featuring it and its prominence in fiction, mythology, astrology and astronomy, acquiring particular importance in many cultures. With telescopes the phases of Venus became discernable and were soon by 1613 presented as decisive evidence disproving the then dominant geocentric model and supporting the heliocentric model. In 1961 the first interplanetary flight was achieved by passing Venus (Venera 1), while only the second flight by Mariner 2 in 1962 returned data. This was followed by the first probe impacting (1967, Venera 4) and landing (1970, Venera 7) on a planet other than Earth. The revealing data about the infernal CO₂ greenhouse effect of Venus raised concerns about global warming and climate change on Earth. As of 2025 the only probe active and reaching Venus is the Solar Orbiter, performing flybys until 2030. The next planned Venus mission is not set to launch before summer 2026 (Venus Life Finder).
